Question

Prakash starts walking from a point A towards South. After walking 40 meters,
he took a left turn. He then walked 30 meters and reached a point B. What is the
straight-line distance between A and B and B is towards which direction of A?
(a) 60 m SE
(6) 50 m SW (c) 50 m SE (d) 60 m SW

Answer 1

Answer:

(c) 50 m SE

Step-by-step explanation:

Prakash walked 40m south and then 30m east. When you join point A and B with a straight line, it will form a right angled triangle. Now, by using Pythagoras theorem,

h^2 = p^2 + b^2

h^2 = 40^2 + 30^2

h^2 = 1600 + 900

h^2 = 2500

h = √2500 = 50
